13th Gate (Baton Rouge, LA)

Located in downtown Baton Rouge, 13th Gate has been used as a film location for photo shoots and movies, such as The Reaping, because of its realistic and detailed rooms. This creepy attraction keeps haunted revelers frightened by revamping its 13 different themes each year. New haunts this year include Possession, an old cabin infested with demonic entities; and Scary Tales, a new feature that pays homage to the famous Grimm Fairy Tales, but it has a 13th Gate twist. “This haunted house is so realistic that you will scream for mercy. It will give you one of the best Halloween experiences in the industry,” says Larry Kirchner, owner and publisher of Hauntworld.com and HauntWorld Magazine.

The Corn Maze at Oakes Farm (Knoxville, TN)

The Corn Maze at Oakes Farm is a less scary, kid-friendly attraction for families who live near Knoxville, TN. Children will enjoy the new Fairy Tale Trail, where kids follow 12 storybook pages as their guide through the kid’s corn maze. This year, the owners have also doubled the size of the corn pit, a huge box packed corn kernels for kids and adults to play. And after 15 years, this Halloween may mark the last time locals and tourists will be able to take the creepy journey along the Trail of Doom. “After several hours in the corn maze, if you happen to find yourself lost -- you may find the sound corn beneath your feet creepy rather than comforting,” says Daniel Schwartz, executive producer of Travel Channel’s TV show Ghost Adventures.

The Darkness (St. Louis)

The Darkness is one of the oldest running haunted houses in St. Louis. This haunted attraction has been updated with new features, including a haunted library filled with evil spirits. The owners have also created the new Scream Zone -- equipped with a mega-scream movie wall and roaming zombies, monsters and demons -- to keep the crowd waiting outside preoccupied. And inside, it’s 2 floors of special effects and more! “The Darkness is considered America’s most detailed and technologically-advanced haunted house in America with over 200 animations, 75 CGI effects, hundreds of zombies, monsters, man-eating puppets and animated effects that grab and bite customers,” says Larry Kirchner.

Eastern State Penitentiary’s Terror Behind The Walls (Philadelphia)

It made our list, Travel’s Best Halloween Attractions 2013, and we decided to add it again this year. Celebrating its 25th anniversary, Eastern State Penitentiary’s Terror Behind The Walls was once home to imprisoned bank robber Willie Sutton and mob boss Al Capone. Today, this penitentiary utilizes its spooky surroundings to create 6 different scare zones, including Quarantine 4D and Breakout, 2 groundbreaking attractions this year. “I’m excited about Breakout, which is a prison break area where inmates – and visitors – attempt to gain their freedom, using barrels, ropes, tunnels and ladders,” says Aaron Sagers, geek culture and paranormal culture expert.

Fear Factory (Salt Lake City, UT)

Located on 2.5 acres or a full-city block in Salt Lake City, UT, the Fear Factory features a post-apocalyptic setting with underground tunnels, towers, mazes and “2 of the largest indoor slides in North America,” according to the owners. For extreme thrills, we suggest the controlled free fall from the factory’s tower or ride the Last Ride zip line to witness the terror from above. Fear Factory, formerly a cement factory built in the late 1800s, is rumored to be haunted by the ghosts of former workers who died here. “People should check out the Fear Factory because this site is one of the rare locations in the US where the history is even more terrifying than that depicted in the haunted house,” says Daniel Schwartz.

The Haunted Trail of Balboa Park (San Diego)

Set in the middle of San Diego is Balboa Park, an idyllic escape from life in the city, but when the sun goes down the monsters emerge on the mile-long Haunted Trail. Beware of creepy characters and horror movie legends such as Freddy Kruger, Michael Meyers and Jason Voorhees. “But, there’s more than just monsters that will spook you, the psychological terrors to make you want to flee the darkness,” says Arthur Hsu, producer of America’s Scariest Halloween Attractions. Visitors can also experience the Experiment, a horrifying maze with more than 3,500 square feet of freak-infested terror. We recommend wearing good running shoes.

Hundred Acres Manor (Pittsburgh, PA)

Hundred Acres Manor offers 6 haunted houses in one location and has been terrifying the victims for over a decade. “With nearly 200 actors you never know when the next scare is going to jump out at you,” says Arthur Hsu. The Vodou Bayou is the new attraction this year. Visitors can take a tour through the Deep South, where the spirits of the bayou beckon, the stitchers want your body, the priestess wants your soul. Dead Lift, Damnation, Torture Bank, The Maze and the Brine Slaughterhouse are the other scary highlights of this bone-chilling haunt. But, there’s a glimmer of light in the darkness, this is a charity scary attraction that donates to Homeless Children’s Education Fund and Animal Friends.

Lord Chaz Ghost & Vampire Tours (New Orleans, LA)

“I like my Halloween scares dished out with a serving of history and a helping of theater,” says Aaron Sagers. “Add in a dash of jazz spirit, and you have the spooky gumbo of Lord Chaz’ Ghost & Vampire Tour in New Orleans.” Lord Chaz – actor, author, musician and street performer – provides guided tours of the French Quarter year round, but his tours are best experienced in October. His Ghost & Vampire Tour starts at Johnny White’s Hole in the Wall on Bourbon Street. On this walking tour, Lord Chaz guides haunted history aficionados through the streets and talks about the infamous murders, suicides and tragedies that have inspired well-renowned authors such as Anne Rice.

Try the new Elevator of Death, where up to 20 people can ride the elevator down to Vault 13, but be prepared for the flickering lights and bumpy descent. “Netherworld is one of Hauntworld’s scariest haunted houses because they spend a long time developing one-of-a-kind costumes, masks, animation and set design that can only be experienced in Atlanta,” Larry Kirchner.
